SPECIFICATION forming part of Letters Patent No. 525,589, dated September 4, 1894.

"0 all whom it may concern: Y

I Se it known that I, FRANK HENRY BURRILL, a citizen of the United States, residing at Concord Junction, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Faucets, of which the following is a specification.

This invention relates to cocks or faucets provided with an auxiliary valve for the purpose of. shutting E the supply of fluid from the main valve when desired, to obviate the necessity of turning 0E the supply from the main when access to the valve or its seat is necessary, for the purpose of making repairs or otherwise, and my invention has for its objectthe production of a more efficient and durable cock or faucet of the class referred v to, simple in construction and cheap to manufacture, and without an opening in thelower portion of the main casing or shell.

In accordance therewith myinvention consists, in a cock or faucet, of a main valve provided with a hollow spindle, a. seat for said valve, an auxiliary valve provided with a stem extended through' the spindle, aseat for the auxiliary valve, and detachable connections between said spindle and stem, to retain the auxiliary valve away from its seat, whereby the spindle and stem are normally rotated and moved longitudinally in unison, substantially as will be described.

. Other features ofmy invention will be hereinafter described, and particularly pointed out in the claims.

Figure 1 is a side view, and for the greater part in section, of a cock or faucet embodying my invention, the main and auxiliary valves beingshown in normal condition. Fig. 2 is a similar view'of the cock or faucet, with the main and auxiliary valves disconnected, and

the latter seated to stop the flow of fluid therethrough. Fig. 3 is a detached view of the main valve and its hollow spindle, and Fig. t is a similar view of the auxiliary valve and its stein.

Referring to Fig. l, the main Valve D is .shown as resting on its seat D2, and preventing the passage of the fluid through the cock or faucet. The valve is provided with a hollow spindle D', having an enlargement D3, herein shown as threaded, to engage the internally threaded hub G, the spindle projecting through a cap or closure Gr' for the hub, and shouldered .or stepped at d, Figs. 1 to 3, for a purpose to be described.

An auxiliary valve E, threaded at F, as

shown in Figs. 1, 2 and 4, is adapted to be screwed into or away from its seat B, the said seat being shaped to receive the shouldered valve E when it is seated, making the valve tight. The auxiliary valve seat B is located below the main valve seat D2, and interposed between the latter and the inlet portion of the cock or faucet, the passage of the duid being indicated bythe arrows in Figs. 1 and 2.

A stem A is secured to or forms part of the auxiliary valve E, of such diameter that it will easily pass through the hollow spindle D', and projecting beyond the upper end thereof, as shown.

The handle C has a hollow shouldered hub C', to fit over the projecting portion of the stem A, as shown iu Fig. 1, the shouldered por-` tions of the hub and the spindle D', being in engagement, whereby rotation of the handle vC in one orthe other direction will cause similar rotation of the spindle, and movement of the main valve D toward or from its seat, to shut o or turn on the fluid.

' A screw H is passed through a washer H on the handle and into the end of the stem A, drawing the shoulder of .the auxiliary valve E up against the under side of the main valve D, and under normal conditions retaining it in such position, the screw H and the handle C forming a detachable connection for the main and auxiliary valves.

From an inspection of Fig. 1 it will be obvious that the auxiliary valve E is always unseated, when connected to the main valve, whether the latter is raised or lowered, and when the main valve is moved away from its seat to turn on the duid the auxiliary valve is moved in unison therewith and out of the passage-way, so that the latter is practically IOO ually prevents the escape of any fluid through the hollowv spindleD, between it andthe. stem A.

By the construction described, thevobjec- ,tionable featuresattendant upon the use of a and the handle C-is reversed, as Vshown in y Fig. 2, and placed on the reduced portion A- of the stem A, which is made square or polygonal, the handle having a correspondingly shaped recess therein, so that it may be used as a wrench.

Rotation of the handle C will cause the auxiliary valve E to move toward its seat B, completelyclosing it, without moving the main valve D, so that the uid is shut off at the cock or faucet, and back of the main valve, as shown in Fig. 2. The cap G can thereafter be removed and the main valve D and its hollow spindle D taken out, and the interior cleaned, or the valve itself may be repaired.

If a new washer is to be inserted, it is slipped down on the stem A until it rests on the top of the auxiliary valve E, and the main valve and stem replaced. When seated, and the cap G in place, the auxiliary valve E can be raised into the position shown in Fig. l, and the handle C reversed. The valves are then again connected byinserting the screw H and the faucet is ready for use.

No skilled labor is required to perform the described operations, and the parts are so few and simple that they cannot get out of order.

By locating the auxiliary valve and its seat as herein described,it is unnecessary to make openings in the faucet shell or casing, for the admission or withdrawal of the auxiliary valve, and this is a most import-ant feature of my invention, for there is no liability to freeze or to leak in a cock or faucet embodying my invention, while in one having such an opening there is always more or less 5o trouble experienced from leakage, or by freezing in cold weather.

While Ihave herein shown my invention as embodied in an ordinary cock or faucet,it

is obvious that its use is not restricted thereto,

for my invention may be applied in other Ways and with other forms of apparatus wherein a valve is employed, by adding an auxiliary valve, its seat, and devices to detachably connect the main and auxiliary 6e valves.-

I claimv Y l. In a cock or faucet, a main valve provided with a hollow spindle, a seat for said valve, Van auxiliary valve provided with a stem extended through the spindle,a seatfor the auxiliary valve, and detachable conneetions between said spindle and stem,to retain the auxiliary valve away from its seat whereby the spindle and stem are normally rotated 7o and moved longitudinallyin unison,substan tially as described.

2. In a cock or faucet, a main and an auxiliary valve seat, a main valve, anV auxiliary valve detachably connected therewith and 15 located below the main valve and between it and the auxiliary valve seat, and means to normally maintain said auxiliary valve adjacent to the under side of and movable with the main valve, substantially as described. 8o

3. In a cock or faucet, a main valve provided with a hollow spindle having ashouldered end,an auxiliary valve provided with a stem extended through said spindle, a washer interposed between said valves and retained in place by the auxiliary valve, a handle adapted to fit onto the stem and to engage the shouldered end of the spindle, and a screw to detachably secure the handle to the stem and maintain it in engagement with 9o the shouldered spindle, substantially as dey scribed.

In testimony whereof I afx my signature in presence of two witnesses.
